Geo-temporal distribution of tag terms for event-related image retrieval
作者：
Highlights：
• We have developed a new approach that effectively retrieves event-based images.
• We have proposed a rigorous technique to extract spatial features from image tags.
• We have developed a method for summarizing spatial distributions of single tags.
• We have developed new techniques for spatial relatedness between two tag terms.
• Our spatio-temporal IR method improves the retrieval performance significantly.
